at the begining of the run i saw how the WR did a glitch where they got knocked into a doorway and then were able to clip into the floor on the roof of the castle. when i tried this myself i couldnt get it to work. i also noticed how he saved and quit when jumping. i tried this as well but it was in f1 of the castle and not b1 like WR. any tips on how to get this clip to work? Thank you to whoever responds.

this wiki pages explains how to get Lonk at the beginning (thats the getting knocked into a doorway glitch) https://alttp-wiki.net/index.php/Lonk

For the uncle jump thing, i'd recommend just joining the discord and asking in there. I'm not aware of a good resource explaining it that I can easily link to.
